IMPROVEMENT IN CAR-COUPLINGS.

Speeication forming part of Letters Patent No. 2l 6.356, dated June 10, 1879; application iled February 28, 1879.

T0 all whom it may concern:

Be it known that we, JOHN G. STIGERs, lsAAo F. BLOOM, and THOMAS J. BOYER, of

the county of Clearfield and State of Penncoupler, being a self-coupler, with link and pin, the same as are now in use on railroadcars.

In the drawings, in which Figure 1 is aperspective view and Fig. 2 a detail View, L is the main shaft. To this is attacheda lever, E, by which the car is uncoupled. To the shaft L is also attached a lever, C, which raises the spring F and withdraws the pin B in uncouplin g. The main shaft is secured by hangers, as represented by M. The pin,when uncoupled, is held in place by a pawl and ratchet, as shown at D and Gr, which prevent it from jarring down, and keep it in constant readiness for coupling.

The coupling is done by the link K coming in contact withl the crow-foot I-l and displacing the lever pawl or dog Gr. The crow-foot holds the link and pin in place when uncoupled, as

shown.

A is the bull-nose or bumper, in which is mortise for the upright lever that raises th spring, as shown at C.

The operation of our device is as follows: The link, entering, strikes the crow-foot H, releasing the pawl G, connected therewith, from contact with the ratchet D, thereby unlocking the shaft M, and permitting it and the lever C to rotate and the spring E to throw the pin B into engagement with the link.

This invention does not interfere with the spring nsedin the old-style couplings. The link now in use is exactly litted to our invention. The pin now used, when attached to spring F by nut, as shown in drawings, is exactly tted to our improvement.

Ourimproved coupler, being self acting, needs no one to guide the link or replace the pin, and consequently no accidents can happen.

Having described our invention, what we claim, and desire to secure by Letters Patent,

The combination of the crow-foot H, pawl G, ratchet D, shaft L, lever C, spring F, and pin B, substantially as described.
